    Matching amps with battery fuse...

    Hey everyone. Installing a system in a jeep cherokee and the guy has a 800w rms pioneer sub amp with dual 40 ampere fuses, and an alpine 4 channel that has dual 20 ampere fuses. I am leaning toward 100-120 ampere fusing at the battery. Would this be ok?

    u fuse for wires amperage capability not for the amps fusing ....contrary to popular belief u are protecting the wire not the amp

    Re: Matching amps with battery fuse...

    ive always just added the number at the battery. and if using a distro block i always get a fused one and use fuse size thats on each amp that the wire is running to. im a noob but i still have yet to blow anything up.

    but say your using zero gauge but you only have a 1000 watt amp. wouldnt that render the 300 amp fuse useless if my amp could never draw that much power?ive always heard use similar fuse that your amp has.

    Call me crazy, but I have a 250 amp fuse for my stock electrical, just cause that's what I had, lol. I don't ghetto rig my stuff and never had a single battery fuse pop.

    But the wire is "4awg ofc" although it's copper colored and is real flexible...I think it was $40 on ebay.

    Well the amplifiers are fused themselves, so I don't see a point in fusing more than at the battery.

    you also have to account if your sub amp does not have a built in fuse

    Because that wire can handle up to 300 amperes, right?

    there isnt a point to fuse the distro besides i get piece of mind, im weird. and incase you ever get a second battery you wouldnt have to buy more fuse blocks. i try to think of future upgrades too save future money lol.

    My 250 amp fuse is for my 2' run of 1/0 OFC. It's about 8" from terminal to fuse holder, than about 12" to the amp input (I'm lucky having the battery in the back)

    Re: Matching amps with battery fuse...

    wow my mistake, so if you are using a 4ga wire and your amp recommends a 200a external fuse, you still use 150a? or do you need to up your 4ga wire?
